I have nothing to add to this except that I saw the headline on Stephen's site, and thought it should be spread to a wider audience:
Bring Back Shields and Yarnell
Okay, actually I have a little more to add; from their Wikipedia entry:
Shields and Yarnell expect to wrap up their "Farewell Reunion Tour" in November 2007.
Sadly, we missed it. But maybe they'll say farewell like Cher and do it a couple more times. Or maybe they'll be trapped in a box and I can catch that. Or a windy street. Or [insert stereotypical, not funny, mime joke here]
